如何限制可变大小窗口的缩小？通过resize处理如下：
Private Sub Form_Resize()
If Me.Width < 1000 Then
Me.Width = 1000
End If
End Sub
这样窗口无法最小化，怎么办呢？

Private Sub Form_Resize()
If me.WindowState=VbMinimized Then Exit Sub

If Me.Width < 1000 Then
Me.Width = 1000
End If
End Sub

最好处理WM_GetMinMaxInfo消息


MSDN:



WM_GETMINMAXINFO
The WM_GETMINMAXINFO message is sent to a window when the size or position of the window is about to change. An application can use this message to override the window's default maximized size and position, or its default minimum or maximum tracking size.

WM_GETMINMAXINFO
lpmmi = (LPMINMAXINFO) lParam; // address of structure

Parameters
lpmmi
Value of lParam. Pointer to a MINMAXINFO structure that contains the default maximized position and dimensions, and the default minimum and maximum tracking sizes. An application can override the defaults by setting the members of this structure.
Return Values
If an application processes this message, it should return zero.

Remarks
The maximum tracking size is the largest window size that can be produced by using the borders to size the window. The minimum tracking size is the smallest window size that can be produced by using the borders to size the window.

QuickInfo
